The LTC2372HUH-18#PBF is a high-performance, low power, 8-bit successive approximation analog-digital converter (ADC), with an integrated precision reference and a parallel host interface, suitable for many data acquisition applications. This article describes the application field of the LTC2372HUH-18#PBF and its working principle.

Application Field of LTC2372HUH-18#PBF

Due to its remarkable features and low power consumption, the LTC2372HUH-18#PBF is suitable for use in many types of data acquisition applications, such as secondary industrial measurement, medical equipment and analysis systems, automotive electronics, military and aerospace projects, telecommunications, consumer electronics applications, and light to medium industrial control. The LTC2372HUH-18#PBF is also well-suited for use in temperature and hall-effect sensors, angular sensing, leak detection, and infrared thermal imaging.

The LTC2372HUH-18#PBF is designed for single-supply operations from supplies as low as 1.8V, making it suitable for battery powered applications. Due to its low power consumption of typically 500 microamps, it does not need bulky external power support, and its integrated power-down function further improves the battery life. The LTC2372HUH-18#PBF can operate up to 64MHz of sampling rates, making it suitable for many high-speed data acquisition applications. The LTC2372HUH-18#PBF incorporates a multi-level measurement signal range of up to 3.3V and a built-in precision reference option, making it ideal for use in high-resolution signal measurement applications.

Working Principle of LTC2372HUH-18#PBF

The LTC2372HUH-18#PBF functions as an analog-to-digital converter, converting an analog signal into a digital signal. The analog input is first converted to a linear-to-digital signal, which is then stored in a parallel host interface. Then, the signal is decimated to an 8-bit digital output, allowing for the output to be evaluated and processed.

The LTC2372HUH-18#PBF is designed with a successive approximation register (SAR) architecture, which converts the analog input signal into a digital signal. The SAR uses a clock to sample the analog input signal, and then repeatedly compares the digital output of the SAR register with the sample of the analog signal, adjusting the reference voltage until the output of the SAR and the analog signal are equal.

The LTC2372HUH-18#PBF also features an internal voltage reference. The reference is used to set the full-scale range of the ADC, as well as to provide the reference voltage used in the SAR process. The reference voltage is also used in a programmable offset feature, which allows the user to offset the analog input signal to optimize the precision of the ADC.

The LTC2372HUH-18#PBF also has integrated temperature and power-down features. The temperature feature allows the user to configure the ADC for optimal output performance in different temperature ranges, while the power reduction feature allows the user to save power by powering down the ADC when not in use.

The LTC2372HUH-18#PBF also incorporates a parallel host interface for output pattern conversion and programmable configurations. The interface allows for direct connection to the host processor and provides code-free portability between different processor platforms. The host interface also allows for the transfer of configuration and measurement data, as well as error interrupts and command acknowledgement signals.

The LTC2372HUH-18#PBF is a low power, high performance ADC, suitable for many data acquisition applications. With its integrated precision reference, parallel host interface and multiple power saving features, the LTC2372HUH-18#PBF is well-suited for use in industrial, medical and aerospace applications, as well as in consumer electronics and other applications that require accurate signal measurement.
